Abstract
- H2-SCR of NOx over W-promoted CezZr1-zO2 solids.
- Specific rate of H2-SCR per surface area is significantly larger in Zr-rich than Ce-rich support composition.
- A large concentration of adsorbed NOx formed does not participate in the H2-SCR.
- N2-selectivities in the 77-92% range were obtained in the 250-450 °C range using 520 ppm NOx/1%H2/5%O2/10%CO2/He.
- H2-SCR activity correlates with total surface acidity of W-promoted CezZr1-zO2 solids.
